OEM Part Number: confirm via VIN — aftermarket Valeo 044186 / TYC 19-0685-11-2

Accuracy note: Covers the Ford B-Max (2012-2017) as listed in the UK aftermarket catalogues. Front fog lights are sold by side on some cars and as a one-size-fits-either-side lamp on others, and the bulb (H11, H8, H16, HB4, H3) and any cornering-light or LED DRL function change the part number. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check whether your trim had fog lights fitted at all (many base trims use a blanking panel), confirm the bulb type against the old lamp, and watch for lamps marked left-hand-drive only.

Fog light, passenger side (LH / nearside) — aftermarket	Valeo 044186 (H8, with bulb, DRL, fits either side); Valeo 088358 (H11, with bulb, fits either side); Van Wezel 1801997 (H8, PGJ19-1, pairs with 1801998); TYC 19-0686-11-2 (H8); Johns 32 66 29 (H8, pairs with 32 66 30); Diederichs 1476089 (H8, pairs with 1476088)
Fog light, driver's side (RH / offside) — aftermarket	Van Wezel 1801998 (H8, PGJ19-1); TYC 19-0685-11-2 (H8); Johns 32 66 30 (H8); Diederichs 1476088 (H8); TYC 19-0177-05-2 (with holder)
Bulb types	H8 (PGJ19-1); H11 (PGJ19-2); H1; P13W (DRL)
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Valeo 044186 and Diederichs 1480088 combine the fog lamp with a daytime running light (H8 plus P13W); both H8 and H11 lamps are listed so check the existing lamp; no cornering versions are listed; bumper-mounted lamps.

A Genuine Diagnostic Shortcut Worth Trying First — Ford B-Max Fog Lights

A genuinely useful diagnostic starting point on the B-Max: pressing the fog light switch and watching whether the dashboard indicator icon illuminates tells you a lot about where the fault actually sits. If the icon lights up as expected but the physical lights themselves stay off, this points to a wiring, connector, or bulb problem downstream of the switch — the switch and its electronics are working correctly, so there's no point chasing a switch replacement. If the icon doesn't illuminate at all, the problem is more likely upstream, at the switch itself or the fuse feeding it.

Worth knowing: the fog light relay on modern Ford models is typically a micro relay built directly into the Body Control Module (BCM) itself, rather than a separate, physically swappable relay like on older cars — if you're expecting to find and test a standalone relay in the fuse box, you likely won't, and this isn't a sign anything's missing.

On the B-Max, two other genuinely common, specific causes worth checking: a wiring harness connector near the fog light that's come loose or was never reconnected properly after bumper or bodywork repair (a surprisingly common cause after any front-end repair work), and, less commonly but still worth ruling out, animal damage to the wiring loom on a car that's spent time parked outside — rodents chewing through wiring insulation is a genuine, if less obvious, cause of exactly this kind of intermittent or total fog light failure.

Ford B-Max Fog Lights: Rarely Used, Easy to Forget About Until Needed

The Ford B-Max's fog lights sit unused for most owners most of the year, which means a fault can go unnoticed for a long time — right up until a genuinely foggy morning makes the problem obvious at the worst possible moment.

Before you buy: fog light fitment and bulb type vary by trim — not every trim level includes them as standard. Always confirm against your VIN before ordering.

Ford B-Max Fog Lights: What It Does

Front fog lights are angled and positioned to illuminate the road surface in low visibility conditions without creating the glare a standard headlight beam would in fog. Some higher trims of the B-Max integrate fog lights into the same housing as cornering lights or daytime running lights, which affects both the part number and the complexity of any repair.

Fitment & Compatibility

Ford B-Max Fog Lights: Generations & Fog Light Type

Standard trims	Halogen fog light bulb as standard
Higher trims, later model years	LED fog lights become available further up the range, genuinely a different assembly and connector from the halogen units on lower trims

Not every trim level of the B-Max comes with fog lights fitted as standard, and the housing design often differs between trims that have them integrated with other lighting functions and those with a standalone unit. Always confirm your specific trim's fitment before ordering. Whether you're sourcing a replacement fog lights for your Ford B-Max from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.
